PEAT-GAS-PRODUCING PROCESS.

Specification of Letters Patent.

Patented Dec. 6, 1910.

Application filed February 4, 1909. Serial No. 476,115.

To all whom it may concern:

Be it known that I, JEAN Dnnriiion OLIGNY, resident of 87 St. Augustinstreet, in the city and district of Montreal, in the Province of Quebec,in the Dominion of Canada, a subject of the King of Great Britain, haveinvented certain new and useful Improvements in Peat-Gas-ProducingProcesses; and I do hereby declare that the following is a full, clear,and exact description of the same.

The invention relates to a peat gas pro ducing process, as described inthe present specification and illustrated in the accompanying drawingthat forms part of the same.

The invention consists essentially in the various steps hereinafter moreparticularly set forth and pointed out in the claim.

The object of the invention is to utilize the peat, so readilyobtainable, in the most economical manner, that is through the cheapproduction of a gas having illuminating as well as heat and powerproducing properties.

The drawing is a view showing merely the outline of the parts to theplant, used in this process.

The first step in the process is destroying the capillary nature of thepeat by placing it under crushing rollers 1 or in fact any suitablecrushing means and during this step saturating the said peat withpetroleum or other hydro-carbonaceous oil 2, then insert ing said peatso pulped and charged with petroleum into a retort 3 heated by thefurnace 3 and baking, until the mass becomes thoroughly coked andrelieved of all the gas and during this step injecting air from thecompressed air reservoir 9 into the said retort, thus warming said airthoroughly and at the same time lading the gas with air, as warm airwill readily mix with the rich peat gas, then passing the gas from saidretort through a carbureting chamber 4: containing tar preferablyobtained as a byproduct from the peat itself, then passing the gasthrough a suitable pipe and through condensing arrangements 6 anddropping the by-products in passage into suitable receptacles 7 andfinally passing the gas into a gasonieter or gasholder 8.

The gas on leaving the retort is, as herel inbefore mentioned, ladenwith air and in this state reaches the carbureting chamber containingthe tar and in this cooled chamber the mixed air and gas is carburetedand much of the tar carried with the gas drops back into the saidchamber from above. The overflow of the tar chamber is taken care of byan overflow passage and receptacle 9 and 10.

The condensing of the gas further on in the process will cause theeXusion therefrom of any further excess of tar and also otherby-products, as also later on in its flow, the

exusion of alcohol, the gas finally reaching the gas holder or gasometerwith its illuminating, heating and explosive properties intact andgenerally in first class commercial condition.

The tar in the carbureting chamber is, of course, in a liquid state asit is being continually fed from the tar by-product dripping from thegas, ascending after it has passed through the said chamber, theoverflow of course flowing through the said overflow passage, whichpassage has a suitable trap therein for sealing purposes.

What I claim as my invention is:

The herein described peat gas producing process, consisting in firsttaking the peat in its natural moist state and crushing, and sprinklingit during said crushing with petroleum oil thus destroying the capillarynature of said peat and producing a pulpy petroleum charged substance,then subjecting said substance to intense heat, then injecting air byforced draft to mingle with the gas from said peat during the step ofcoking JEAN DELPHIOE OLIGNY.
